Tumble Dryer Not Heating How to Fix It in Totton

Published September 2026 | Tumble Dryer Repair

What Causes a Tumble Dryer to Stop Heating

When your tumble dryer runs perfectly well - the drum turns, the timer counts down - but your clothes come out cold and damp, the problem is almost always somewhere in the heating circuit. Understanding what sits inside that circuit helps you make sense of what's gone wrong.

The heating element is the most common culprit. In a vented or condenser dryer, this is a coiled wire element that glows red-hot to warm the air drawn through the machine. Over time, particularly in older Hotpoint, Indesit, and Beko machines, the element wire fractures and the circuit breaks. No circuit, no heat. It's the same principle as a blown filament in an old light bulb.

Thermal fuses and thermostats are the next most frequent failure point. These are safety devices built into every dryer specifically to cut the heating circuit if temperatures climb too high. A blocked lint filter or a kinked exhaust hose causes heat to build up rather than vent away, and the thermal cutout does exactly what it's designed to do - it trips and shuts off the heating element to prevent a fire. The problem is that on many machines this component doesn't automatically reset. It stays blown, and your dryer stays cold, even once you've cleared the blockage that triggered it in the first place.

Thermistors - temperature sensors that feed real-time readings back to the control board - are also a known failure point, especially in newer Bosch, Samsung, and LG models that use more complex digital controls. If the thermistor sends a faulty reading suggesting the drum is already at temperature, the board never activates the element.

On heat pump dryers, which are increasingly common across homes in Totton and the wider Hampshire area, the heating mechanism is completely different. There's no traditional element at all. Instead, a refrigerant circuit captures and recycles heat, similar to a reverse air conditioning unit. When these fail to heat, the causes include refrigerant leaks, a faulty compressor, or a blocked evaporator - all of which require a specialist engineer.

Finally, don't overlook the control board itself. A failed relay or a software fault on the board can prevent the heating circuit from activating at all, even when every individual component in that circuit is fine. This is a less common fault, but our engineers see it regularly in higher-end machines from Miele and AEG.

How to Diagnose the Problem Step by Step

Before you call an engineer or buy any parts, run through this diagnostic sequence. You'll be able to tell an engineer exactly what you've found, which saves time and often saves money on the call-out.

1. Check the lint filter first. Pull it out - it's usually inside the door opening - and check whether it's clogged with fluff. A completely blocked filter restricts airflow so severely that the thermal cutout will trip within minutes of the machine starting. Clean it thoroughly, then run a short cycle to see if heat returns.
2. Inspect the exhaust duct. If you have a vented dryer, trace the flexible hose from the back of the machine to wherever it vents outside. Look for kinks, blockages, or a vent cap that's been pushed shut by wind and stuck. Disconnect the hose and check inside it for compacted lint - this is one of the most common causes of repeat thermal fuse failures we see in Totton properties.
3. Check your condensate drawer. If you have a condenser dryer, the condensate drawer at the top of the machine needs to be emptied regularly. An overfull drawer won't directly stop heating, but it can trigger sensors in some machines to pause the cycle mid-run.
4. Listen to the machine running. Does it sound normal? A dryer drum turning but the machine running unusually quietly might suggest the motor is running but the heating element relay isn't engaging. A burning smell during a brief test run suggests the element may be partially failed and arcing.
5. Use the Voltrade GoFIX diagnostic tool. Enter your dryer's make, model, and the specific fault code if one is displayed on the panel. GoFIX will narrow down the most likely fault components for your specific machine, which is particularly useful for newer Samsung and LG dryers that display digital fault codes.
6. Check for a reset button. Some dryers, particularly older Hotpoint and Creda machines, have a manual reset button on the back panel near the exhaust outlet. Press it, wait thirty seconds, and try a cycle again. If it trips again quickly, there's still a restriction or a failing component causing the overheat.

Once you've worked through this list, you should have a reasonable idea of whether the problem is something you can sort yourself or whether you need an engineer.

DIY Fixes Versus Calling a Professional

Some tumble dryer repairs are well within the capabilities of a reasonably practical homeowner. Others really aren't, either because they require specialist tools or because getting them wrong creates a genuine safety risk.

What you can safely do yourself

Cleaning the lint filter and exhaust duct is something every dryer owner in Totton should be doing every few months anyway. It costs nothing, takes five minutes, and is responsible for a significant proportion of the no-heat calls our engineers attend. If your dryer comes back to life after a thorough clean of the duct and filter, that's your fix - no parts required.

On some vented dryers, particularly older Beko and Indesit models, the thermal cutout is accessible through the back panel, which is held on with a few Phillips screws. If you're comfortable working with the machine fully unplugged and you can identify the correct replacement thermal fuse for your exact model, fitting a new one is a manageable job for someone who's confident with basic DIY. Replacement fuses typically cost between 8 and 20 pounds for the part alone.

When to call an engineer

Heating element replacement is usually the sensible boundary for most people. The element itself is accessible once the back panel or top panel is removed depending on your model, but on machines like Bosch Series 6 dryers or Samsung DV models, access can be awkward and there's meaningful risk of damaging other components if you're not familiar with the layout. An incorrectly fitted element can also create a short circuit.

Anything involving a heat pump dryer, a control board, or any gas appliance should always go to a professional. Gas tumble dryers are less common in the UK than vented or condenser models, but if you have one, gas work must be carried out by a Gas Safe registered engineer - this is a legal requirement, not just a recommendation.

If your machine is still under manufacturer's warranty, don't attempt any internal repair yourself. You'll void the warranty. Contact the manufacturer directly or use an authorised service centre.

What a Qualified Engineer Will Do

When one of our engineers attends a no-heat call in Totton or elsewhere in Hampshire, the process follows a consistent pattern that gets to the root cause efficiently rather than just replacing parts until something works.

The first step is always a visual inspection and a check of the duct and filter condition, for exactly the reasons covered above. You'd be surprised how often the cause is something the homeowner could have caught with a torch and ten minutes.

From there, the engineer will use a multimeter to test continuity across the heating element, the thermal fuse, the thermostat, and the thermistor in sequence. A component that shows no continuity when it should is a failed component, and that's what gets replaced. This approach means you're only paying for the part that actually failed, not working through a list of possibilities.

On machines that display fault codes - increasingly common in Samsung, LG, and Bosch machines - the engineer will read and interpret those codes first. Some codes point directly at the failed component. Others are more general, but they still help narrow the diagnostic field.

Once the replacement part is fitted, the engineer will run the machine through a full drying cycle and check airflow, final temperature, and cycle completion before signing off the repair. On condenser dryers, they'll also check that the condenser unit itself is clean and that airflow through the evaporator is unobstructed.

A thorough job typically takes between 45 minutes and 90 minutes on site, depending on the machine and what's found.

Costs and What Affects the Price

Appliance repair pricing in Totton follows a broadly consistent structure across most engineers, though there's variation between traders. Understanding what drives the cost helps you assess whether a quote is reasonable.

Most engineers charge a call-out or diagnostic fee, which typically falls between 50 and 80 pounds. This covers the visit and the diagnosis. Some traders fold this into the total repair cost if you proceed; others charge it as a separate fixed fee regardless.

Parts are then charged on top. A replacement heating element for a common Hotpoint or Beko vented dryer typically costs between 25 and 55 pounds for the part. A thermal fuse is usually 8 to 20 pounds. Labour to fit the part is typically a further 30 to 60 pounds depending on the complexity of access and how long the job takes.

All in, the most common repairs - element or thermostat replacement - typically come to between 100 and 200 pounds including call-out, parts, and labour. More complex repairs involving control boards can reach 200 to 300 pounds, at which point you're approaching the cost of a budget replacement machine and it's worth discussing the repair-versus-replace question with your engineer.

Heat pump dryers cost more to repair than conventional vented or condenser dryers. The components are more expensive and the engineering is more complex. A heat pump dryer repair in Hampshire can realistically run to 250 to 450 pounds for faults involving the refrigerant circuit or compressor.

A few factors that push the price up: older machines where parts are scarce and need to be sourced specially; premium brands like Miele or AEG where components carry a higher price; and machines that require significant disassembly to reach the failed component.

One useful rule of thumb: if the repair is going to cost more than half the price of a comparable new machine, replacement is usually the better financial decision unless the machine is relatively new or high-spec.

How to Prevent Your Dryer Losing Heat in Future

Most no-heat faults in tumble dryers are preventable with regular, simple maintenance. These aren't complicated jobs - they're the kind of five-minute tasks that most people skip until something goes wrong.

Clean the lint filter after every single load. Not every week, not when you remember - every load. The filter collects an enormous amount of fluff from a single drying cycle, and even a partially blocked filter starts to reduce airflow efficiency. For homes in Totton with families running multiple loads per week, this makes a real difference.

Clean the full exhaust duct every three to six months. Disconnect the hose from the back of the machine and use a long, flexible brush or even a vacuum cleaner with an extension to clear compacted lint from the full length of the duct. Check the external vent cap while you're at it.

On condenser dryers, clean the condenser unit itself. This is usually accessed behind a panel at the bottom front of the machine. Rinse it under a tap and allow it to dry fully before refitting. Doing this every one to two months prevents the efficiency losses that cause overheating faults.

Don't overload the drum. A drum that's too full restricts airflow through the load, causes the machine to run longer than it should, and puts additional strain on the heating circuit and motor. As a general guide, the drum should be about half to two-thirds full for efficient drying.

Keep the area around the machine clear. Dryers need room to breathe. Don't push them flush against a wall that blocks the exhaust, and don't pile laundry on top of a condenser dryer in a way that blocks air intake grilles.

Frequently Asked Questions

Why is my tumble dryer running but not getting hot?

The drum running with no heat almost always points to a fault in the heating circuit specifically, rather than the machine as a whole. The most likely causes are a failed heating element, a blown thermal fuse, or a faulty thermostat. A blocked lint filter or exhaust duct can also trigger the thermal cutout, cutting heat while leaving the drum motor running normally. Start by checking airflow before assuming a component has failed.

Can I replace a tumble dryer heating element myself?

It's possible on many common machines, particularly older Beko, Indesit, and Hotpoint vented dryers where the back panel is easily removed. You'll need to buy the correct element for your exact model number and be confident working with the machine completely unplugged. That said, on newer machines with more complex layouts, or any condenser or heat pump dryer, it's more sensible to have an engineer do it to avoid damaging other components during disassembly.

How much does a tumble dryer repair cost in Totton?

For the most common faults - a failed heating element or thermal fuse - expect to pay between 100 and 200 pounds all in, covering the call-out, parts, and labour. More complex repairs involving control boards or heat pump components typically run higher, between 200 and 400 pounds. If the repair cost is approaching half the price of a comparable new machine, it's worth discussing whether replacement makes more financial sense.

Is it worth repairing an older tumble dryer that's stopped heating?

It depends on the age and quality of the machine. A well-built machine from Bosch, Miele, or AEG that's eight to twelve years old and needs a standard heating element is almost always worth repairing - the cost is modest and the machine has plenty of life left. A budget dryer that's over ten years old with multiple signs of wear is harder to justify repairing at full cost. Ask your engineer for an honest assessment of the machine's overall condition before committing.

Why does my tumble dryer keep losing heat after it's been repaired?

Repeat heating failures are almost always caused by a restriction in airflow that hasn't been fully resolved. If the duct is even partially blocked, the thermal fuse will trip again within a few cycles. Sometimes there's also a secondary fault - for example, a thermostat that was already weakened and fails shortly after the element is replaced. If your dryer in Totton or anywhere in Hampshire loses heat again within a few weeks of repair, insist on a full airflow and thermostat check, not just another element replacement.
